Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is, for example, a stopper attached to a decorative string or chain used as a necklace, bracelet, anklet, or the like, and the length of the decorative string or chain can be adjusted. The present invention relates to a fastener such as an accessory cord or chain that can be held at an arbitrary position.

[Prior art]

 2. Description of the Related Art Conventionally, various types of fasteners such as strings and chains for decoration have been provided, for example, a fastener and a string described in Japanese Patent No. 3114868. Stopping devices have already been disclosed. This is a stopper including an outer shell and an elastic body, wherein the outer shell has a hole and a hollow portion, and the inner wall surface of the hollow portion is a continuous body having a spherical shape. The hole communicates from the outside of the outer shell to the hollow portion, and the elastic body is an O-ring-shaped member having a through hole, which is built in the hollow portion and has an outer periphery. Is in pressure contact with the inner wall surface of the hollow portion, the through-hole portion communicates with the hole, and the elastic body passes through the hole of the outer shell body and is inside the outer shell body. It is introduced to.

[0003]

[Problems to be solved by the invention]

 However, in the stopper and the strapping device as described above, hooking means using a wire or the like is hooked on the elastic body, which is an O-ring-shaped member, and the inside of the outer shell is passed through the hole of the outer shell. However, since an O-ring-shaped elastic body is introduced into the apparatus, there has been a problem that the operation of introducing the elastic body itself is unexpectedly troublesome. In addition, since the elastic body is hooked by the hooking means and introduced into the outer shell, at the time of introduction, the direction of the through hole of the elastic body is substantially orthogonal to the direction of the hole of the outer shell. However, there were difficulties such as the necessity of a correction work for correcting the orientation of the elastic body so that the direction of the through-hole portion matches the direction of the hole of the outer shell, and the time required for the correction work. Furthermore, in the case of a relatively thin O-ring-shaped elastic body, if a part thereof is cut due to, for example, friction with the string member or aging deterioration, the cut end portion becomes the outer shell hollow part. There is also a drawback that the tightening force of the string member by the elastic body becomes extremely weak.

The elastic body B is formed in a substantially spherical shape that is relatively large elastically deformed by a rubber material, a resin material, a composite material, or the like as appropriate. Moreover, the size of the elastic body B is determined by, for example, that when three elastic bodies B are provided inside a substantially hollow spherical outer shell A, the outer surfaces of the three elastic bodies B circumscribe each other, The size of the elastic body B is set so that the outer surface of the elastic body B is inscribed with the inner surface of the outer shell body A, so that the three elastic bodies B can be stably and well-balanced within the outer shell body A. is there. As a result, the elastic compression state of the strings / chains C in the surrounding space 2 is more stable and the balance is improved, and the strings / chains C are kept in a state where the strings / chains C are securely pressed and held. Are configured to slide with respect to the elastic body B without difficulty.

In addition, the elastic body B is appropriately formed into a hollow shape (not shown) so that the elastic body B itself becomes larger and easily elastically deformed. You may comprise so that it may be put in A more smoothly. Thus, the interior work of the elastic body B in the outer shell body A can be easily performed, the work efficiency can be improved, and the elastic pressing force on the string / chain C by the elastic body B can be adjusted.
